Found some keepers from the Brickyard Grand Prix practice day. If you look really closely, you'll see 2 former F1 drivers. Hint, both of their last names start with "B."
One of the F1 drivers is in the #77...
The other former F1 racer is in the #4.
The two Starworks cars together.
Kinja decided this picture shouldn't be next to the other picture of the off.
